    It is also ideal for measuring substances susceptible to vapor formation and liquids with gas blankets. As no medium is required for millimeter wave propagation, it can also be used in a vacuum. The device can also be operated with HART compliant NIVELCO EView2, MultiCONT universal process controller, and PACTware™ software, or programmed ® via Bluetooth communication with the new MobileEView app.

  • Page 36 Error indication delay: This parameter defines the time elapsed between the occurrence of the error and the issued error signal (error current). During the delay, the output is holding the last valid measured value. The function is available for current output only if the error signal is set to a lower (3.8 mA) or upper (22 mA) error current. When the error is gone, the device returns to measuring mode after the set delay.
